function 的输入和输出 void *function(){}

Question

A void function does not return any value as output and can take input values. The function below seems a void function, but there is the operator *, why?

void *function(){
     printf("hello")
}

Answer 1

That is not a void function. That is a function that returns a void* (pointer). But it seems incomplete, because the printf() has no semicolon ; and the function does not actually return a void* .
